Abstract

La présente invention se rapporte au domaine technique de l'information. L'invention concerne un appareil et un procédé de traitement de signal sans fil, un module de conversion sans fil, un routeur et un équipement d'utilisateur qui peuvent considérablement diminuer la complexité de traitement d'un signal sans fil. Un module de conversion sans fil reçoit tout d'abord un ordre de réception envoyé par un routeur et qui porte une fréquence de réception et une fréquence d'échantillonnage ; puis reçoit, en fonction de la fréquence de réception, un signal sans fil correspondant à la fréquence de réception ; et enfin, réalise un traitement d'échantillonnage sur le signal sans fil, de manière à obtenir un signal numérique, puis envoie le signal numérique au routeur. La présente invention peut être appliquée à un cas dans lequel un module de conversion sans fil, un routeur et un équipement d'utilisateur reçoivent et traitent un signal sans fil en fonction d'un ordre de réception envoyé par l'équipement d'utilisateur, de manière à obtenir des informations requises par l'équipement d'utilisateur.
